Last few months i was completely working with GNU Radio and LimeSDR mini for a small project in which i wanted to send data using some QPSK Modulation. But this device is not able to modulate the baseband signal properly so that i am unable to receive any file at file sink block. Further i tried with GMSK and GFSK modulations, the device transmits it very efficiently. Also i used another SDR (HackRF One) with my same design and i was receiving a proper data at receiver end. So i concluded that it is problem with the Hardware which is not able to modulate it properly.
Can you please find me a solution for this so that i could use QPSK modulation in LimeSDR.
Any drivers have to be updated in GNU Radio??
Thanks & Regards,
